Pasteboard convenience moves data beyond the application's boundary. Automatically copying persistent secrets is a poor default.
Evaluation approach
Tie copying to explicit user action. Choose content scope and available lifetime options according to need.
Application example
A public wallet address and a recovery phrase have very different sharing consequences. Make that distinction visible.
Limits and considerations
Do not assume complete control over copies in other applications.
Helping users decide
Copy buttons on sensitive fields should not produce unexpected consequences. Distinguish shareable addresses from recovery secrets. Explicit action reduces accidental transfer but does not guarantee recall of another application's copy.
Checks and decisions
- Separate secrets
- Remove automatic copying
- Explain sharing context
